What God told Abraham while he was in Canaan in Genesis 15:13-16 generations before Moses:
‘Then the Lord said to him, “Know for certain that your descendants will be strangers in a country not their own, and they will be enslaved and mistreated four hundred years. But I will punish the nation they serve as slaves, and afterward they will come out with great possessions. You, however, will go to your fathers in peace and be buried at a good old age. In the fourth generation your descendants will come back here, for the sin of the Amorites has not yet reached its full measure.” Genesis 15:13-16
What God told Moses, God’s chosen instrument to deliver Israel from the Egyptian captivity:
‘Then the Lord said to Moses, “See, I have made you like God to Pharaoh, and your brother Aaron will be your prophet. You are to say everything I command you, and your brother Aaron is to tell Pharaoh to let the Israelites go out of his country. But I will harden Pharaoh’s heart, and though I multiply my miraculous signs and wonders in Egypt, he will not listen to you. Then I will lay my hand on Egypt and with mighty acts of judgment I will bring out my divisions, my people the Israelites. And the Egyptians will know that I am the Lord when I stretch out my hand against Egypt and bring the Israelites out of it.” Exodus 7:1-5
When Moses and Aaron confronted Pharaoh and told him what God had told them to say to Pharaoh to “let my people go”, the battle had only just begun between Pharaoh and God. It was a human will bent on doing evil compounded by his allegiance to Satan to carry out his will. It is very clear from generations before what was foretold to Abraham that the nation of Israel was going to come out of their slavery in a foreign country as a people to worship the True and Living God in the Promised Land. Egypt was known to practice divination and sorcery, practices that are abominable to God as these are practices related to worshiping Satan. We can read that from Joseph’s silver cup that he used for divination while he was in Egypt that was left on purpose in Benjamin’s sack. Pharaoh consulted with wise men, sorcerers, Egyptian magicians and tried to duplicate the plagues of God inflicted on Egypt through the use of their “secret arts”. Pharaoh had a heart and will that was bent on doing evil and doing the will of Satan. He would not be convinced through God’s miraculous acts to show Himself as Lord to Egypt. While on one hand, a sinner can only be drawn by God to have faith in Him, all humans though marred by the sin nature and lost in depravity still know the difference between good and evil. Depravity from the sinful nature does not mean sinners are incapable of doing and being good but that we cannot on our own accord choose to believe God through Christ who came to make us holy, not just good. This experience is the initiative of God through the regeneration of the Holy Spirit with the Gospel of Christ. Pharaoh determined and bent on doing evil and harm to Israel as a people subjected his own Egyptian people to God’s judgment through the 10 plagues God inflicted on Egypt. It was within Pharaoh’s power to do what was right and good to let Israel go free but he willfully chose not to.
Due to such evil in Pharaoh’s heart, God withheld His mercy from Pharaoh. God withheld the mercy that is needed for a sinner lost in depravity to be quickened in his dead spiritual senses to respond in order to believe and trust God. God’s act of salvation is an initiative of God showing us mercy or we will forever be condemned unable to respond to God through faith in Christ. That mercy of God denied to Pharaoh can be referred to as God hardening Pharaoh’s heart. Pharaoh could not respond to God in repentance and faith plague after plague performed by Moses because God had withheld His mercy from Pharaoh. The rebellious, unrepentant heart of Pharaoh could be seen through how he pursued the people of Israel to the crossing of the Red Sea where God drowned all the Egyptians, their chariots and horsemen. Through Israel’s Egyptian captivity God’s intention was to show Israel His great power so that they will fear the LORD and put their trust in Him. (Exodus 14:5-31) That was God’s will and God accomplished His will which could never be thwarted when He worked around and used the evil of Pharaoh bent on serving Satan’s will to destroy Israel as a people. God displayed His glory before Egypt which was received with no repentance due to God’s hardening of Pharaoh because God withheld showing mercy. Through that same display of God’s glory, God showed mercy to Israel which then led to Israel’s fear and trust in the LORD. The Sovereign God in His infinite wisdom work within His purposes the use of existing evil in the world to display His glory to accomplish His will.
God was not responsible for Pharaoh’s sinful, wicked and evil behavior. God included within His purposes Pharaoh’s depravity with all the capacity to do harm and evil to wisely bring glory to Himself in order to accomplish His Sovereign will in the calling and making of Israel as His chosen people. Pharaoh’s evil was raised and used by God for the very purpose of displaying His power to Israel and to the earth. God could have struck Pharaoh dead but He withheld such judgment and showed forbearance instead for the sake of Israel whom He had sovereignly chosen to be their God and to make them His people .
The example of Pharaoh’s hardening of heart is in no way a precedent to determine God’s mind of who He has not chosen to receive His gift of salvation. It is also not to teach that it is within the power of the human will to decide whether to believe or reject God. It also does not teach God’s choice base on the deserving over the undeserving. Instead, it shows that God is the Sovereign God who alone has the prerogative to choose based on His sovereign choice. God has sovereignly chosen His the elect to receive mercy. God’s mercy is the basis of choosing the elect and not justice or fairness. This should lead us gratefulness because we are all undeserving apart from His mercy.
Romans 9:14-16 “What then shall we say? Is God unjust? Not at all! For he says to Moses, ‘I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.’ It does not, therefore, depend man’s desire or effort, but on God’s mercy.
Romans 9:17-18 “For the Scripture says to Pharaoh: ‘I raised you up for this very purpose, that I might display my power in you and that my name might be proclaimed in all the earth.’ Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden.”
Romans 9:19-21 “One of you will say to me: ‘Then why does God still blame us? For who resists his will?’ But who are you, O man, to talk back to God? ‘Shall what is formed say to him who formed it, ‘Why did you make me like this?’ Does not the potter have the right to make out of the same lump of clay some pottery for noble purposes and some for common use?”
Romans 9:22-24 “What if God, choosing to show his wrath and make his power known, bore with great patience the objects of his wrath – prepared for destruction? What if he did this to make the riches of his glory known to the objects of his mercy, whom he prepared in advance for glory – even us, whom he also called, not only from the Jews but also from the Gentiles?”
God’s sovereign choice of the elect is based on mercy and one can only be drawn by God in order to respond to Him through Christ. God’s objects of wrath are such because they have not been drawn to believe in Christ. It is beyond us why only some belong to God’s elect and while others are not. God’s elect, those sovereignly chosen to receive God’s gift of salvation through Christ are chosen based on God’s mercy while the condemnation of objects of God’s wrath is due to sins. It is sin and not God that condemns mankind to hell. Those who are not objects of God’s mercy are objects of wrath with hearts that are harden towards sin and evil. God’s mercy to the elect leads to holiness and serving God’s will and purposes, doing the good works which God prepared in advance for us to do. “For it is by grace you have been saved, through faith and this not from yourselves, it is the gift of God – not by works, so that no one can boast. For we are God’s workmanship, created in Christ Jesus to do good works, which God prepared in advance for us to do.” Ephesians 2:8-10
